Why does an app with a privileged helper tool need an Override?
Short answer: Its privileged helper is tied to the app's location, so moving the app may break the helper on its next update. Storage Studio asks you to confirm; leaving such apps in place is usually safer.
Some apps install a separate helper that runs with extra privileges and is tied to the app's exact location — VPNs, backup tools and system utilities often do. Moving the main app can break that link the next time the app reinstalls or updates its helper.
Storage Studio shows the reason and lets you decide. For apps like these, leaving them on your built-in drive is usually the safer choice.
